Answer:
Volume of the solid is 377 cm³.
Step-by-step explanation:
Volume of the cylinder = 
Here, r = radius of the cylinder
h = Height of the cylinder
By substituting the values in the formula, (r = 4 cm and h = 10 cm)
Volume of the cylinder = 
= 160π
Since one fourth of the cylinder is removed,
Volume of the remaining cylinder = 160π - 
= 160π - 40π
= 120π
= 120(3.14)
= 376.8 cm³
≈ 377 cm³
Volume of the solid is 377 cm³.
